Compared with stoopeed people, do you think those who are very intelligent and know things can, and/or do, make larger mistakes than the less-clever person? Perhaps to force biases in your thought/opinion reply (so you might not want to read this list) or to encourage inspiration in your reply -
"blondes have more fun" and are more air-head-y/ditsy
The cleverer a person is, the more depressed they are, so they therefore could make more mistakes,
a person who understands a lot of things could not possibly be making bigger mistakes,
"for a clever person, you get an awful lot of things wrong/make an awful lot of mistakes",
with a person understanding more things, they could miss small details which could derail things entirely (e.g. "the big bang theory" being so very big and so very incorrect),
some very clever individuals might be stretching their minds too thinly,
The less-clever a person is, the less responsibility they have, the less things they do/are concerned with, the less they focus on; therfore, the less mistakes they make because they do the same few things often and repeatedly, which they perfect, which could mean that they are brighter than you in some ways
